Application fi1ed-Januar'y24, 191d, Serial m5; 539,683.

To allwhom it my Com-em:

Be it known'tha't I, WILLIAM BELL, a citizen of the United States,residing at Bakersfield, in the county of Kern and State of California,have invented new and useful Improvements in Rope-Sockets, of which thefollowing is'a specification.

The object of the pre sent invention is to provide a 'rope socketwhich-shall ,be

interchangeable for different kinds of tools. It is especially adaptedforconnecting the rope to a hook for raising the sucker rods and tubingofoil wells, and also for the stems of jarring tools. and cleaning outstrings.

In the accompanying drawing, Figure 1 is a vertical section'of thedevice; Fig. 2 is a horizontal section on the line 22 of Fig. 1; Fig. 3is a"similar section on the line 3-3 of Fig. l. p I

Referring to the drawing, 1 indicates a socket proper, the aperture 2 ofwhich is expanded at the lower portion. In said aperture is insertedtherope or cable 3, the strands of which are frayed out, and aresecuredin said aperture by means ofBabbitt metal 4 or any suitable materialcast or allowed to set therein. Said socket is formed with an upwardlyfacing exterior annula-r shoulder 5. 6 indicates the'tool which is to besupported by said socket, whichis here shown as a hook for attachingto'the elevators or other devices for raising the sucker rods or tubing.Said hook isformed with an annular groove 7, the upper side of whichforms a downwardly facing annular. shoulder. Surrounding the lowerportion of the socket and the upper portion. of the tool are twosemi-cylindrical sleeve sections 8 which when placed together form asleeve having a downwardly facing shoulder 9 resting upon the shoulder5, and the lower portion thereof being reduced in diameter,

as shown at 10, to enter the groove 7. One of said sections is securedto the lower portion of the socket by a screw 11, and is not removed inordinary use. The sleeve sections are formed near the lower end with tothe sleeve sections and which extend J ,a rifexternal shoulder J2 andsurrounding @saidsleevesections i's'a tube 13, slid over said' sleevesections when in place; It is retained against upward movement by twowashers 14 which are secured by screws 15 over the upper'end of thetube. '.I'n operation,'the hook is fitted in the sleeve, sectionpermanently secured to the socket, and then the othersleeve section isplaced around the hook and socket, so that the parts 10 of the sleeveenter the groove- 9 in the-hook, and the shoulder in the upper PatentedJuly 11, 1911.

portion of thesleeve 9 rests upon the shoulder 5;on'the socket. The tube13 is then passed longitudinally on to the sleeve, and the washers Maresecured in place by the screwslfi. The hook is "removed by a reverseoperation. v

By this means a is. possible, infuse with an 011 well, to-r'emovethe-rods, remove the tubing, apply the string of cleaning tools to cleanthe well, then replacethe tubing, and replace the ,rods, allwith singlelineof rope.

In combination withfa socket having a longitudinal aperture enlarged atthe lower endgand having an upwardly facing-external shoulder, sleevesections'havi'ng downwardly facing internal shoulders adapted to restupon said shoulder, and upwardly facing internal shoulders adapted toengage a downwardly facing shoulder on a tool to be supported, saidsections'each having an upwardly facing external shoulder, a tube aroundsaid sections and resting against said external shoulders, and means forretaining said tube against upward movement on said sections,substantially as described. Y

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
